Where to find your AirTag battery status

Your iPhone or iPad shows your AirTag's battery level in the Find My app. Open Find My, tap the Items tab at the bottom, select your AirTag from the list, and look at the battery percentage displayed under the AirTag's name. That percentage updates whenever your AirTag connects to a nearby Apple device, so the reading is usually current within a few hours.

If you see a low battery warning instead of a percentage, your AirTag has less than 10 percent charge remaining. At that point, you have days or weeks left depending on how often the AirTag is detected, but you should plan to replace the battery soon.

The Find My app is the only place Apple provides battery information for AirTags. Third-party apps cannot read this data, and the AirTag itself has no screen or indicator light to show you the charge level.

Key Takeaways

  • Open Find My on your iPhone or iPad, tap Items, select your AirTag, and read the battery percentage shown under its name.
  • The battery percentage updates when your AirTag connects to nearby Apple devices, so it may lag by a few hours.
  • A low battery warning appears when charge drops below 10 percent, giving you time to replace the battery before it dies.
  • AirTag batteries last roughly one year under normal use, and you replace them yourself with a standard CR2032 coin cell battery.

What the battery percentage actually means

The percentage shown in Find My reflects the charge level the last time your AirTag communicated with an Apple device. If your AirTag is in a drawer and hasn't been near an iPhone, iPad, Mac, or Apple Watch for several days, the percentage may be older than you think. The app does not actively check the battery — it only updates when the AirTag sends a signal.

A reading of 50 percent does not mean your AirTag will stop working in half the time it took to reach 50 percent. Battery drain is not linear. An AirTag at 50 percent may run for several more months, while one at 10 percent may last only days or weeks. The exact timeline depends on how often the AirTag is detected and how far it travels.

When to replace your AirTag battery

Replace the battery as soon as you see the low battery warning. You do not have to wait until the AirTag stops responding, and waiting risks losing track of an item when the battery dies unexpectedly. A fresh battery takes about 30 seconds to install.

To replace the battery, press down on the stainless steel back of the AirTag and twist counterclockwise until the cover pops off. Remove the old CR2032 battery, insert a new CR2032 with the positive side facing up, and twist the cover back on clockwise until it clicks. CR2032 batteries cost a few dollars and are sold at pharmacies, electronics stores, and online retailers.

Under normal use — checking on a bag or keys a few times a week — a single CR2032 battery lasts roughly one year. Heavy use, such as tracking a frequently-moved item, drains the battery faster.

Troubleshooting a battery that drains too fast

If your AirTag's battery drops from full to low in a few weeks instead of months, the AirTag may be detecting constantly. This happens when an AirTag is in a location with many Apple devices nearby, such as an office or apartment building. The AirTag broadcasts its location more often in crowded areas, which uses more power.

Moving the AirTag to a less crowded location or using it less frequently will slow the drain. If the battery still depletes unusually fast after a few weeks in a different setting, the AirTag itself may be faulty. Contact Apple Support with your AirTag's serial number and the dates you installed and replaced the battery.

Why Find My sometimes shows no battery information

If Find My displays your AirTag but shows no battery percentage, the AirTag has not connected to any Apple device since you last opened the app. This is normal if the AirTag has been offline for days. Open Find My again in a few hours or move the AirTag closer to your iPhone, and the percentage should appear.

If an AirTag shows as offline in Find My and never displays a battery percentage, the battery may be completely dead. Replace it with a fresh CR2032 and the AirTag should reconnect within a few minutes. If it still does not appear after a new battery, the AirTag may have a hardware problem and should be replaced.

Checking battery on a shared AirTag

If you share an AirTag with family members through Find My, only the person who set up the AirTag can see its battery level. Other family members can see the AirTag's location but not its charge status. This means one person in the household should check the battery regularly and handle replacements.

You can change who manages the AirTag by removing it from your account and having another family member set it up instead. That person will then see the battery percentage and be responsible for replacements.

Frequently Asked Questions

How often should I check my AirTag's battery?

Check the battery once a month or whenever you open Find My for other reasons. Most AirTags run for a full year, so monthly checks give you plenty of warning before the battery dies. If you use the AirTag heavily or it is in a crowded area, check every two weeks.

Can I use a different type of battery in my AirTag?

No. AirTag requires a CR2032 coin cell battery specifically. Other battery types will not fit or work. CR2032 batteries are standard and inexpensive, sold everywhere from grocery stores to online retailers.

What happens if my AirTag battery dies?

The AirTag stops broadcasting its location and Find My will show it as offline. You can still see its last known location in the app, but you cannot track it in real time. Replace the battery and it will reconnect within a few minutes.

Does cold weather affect AirTag battery life?

Cold temperatures can temporarily reduce battery performance, but they do not permanently damage the battery. An AirTag in a cold car or outdoor location may show a lower percentage than it actually has. The reading usually returns to normal once the AirTag warms up.
